Calculate dawn, dusk, golden and blue hour times by using various algorithms.
### Twilight Types

## Usage
Some examples:
```swift
import Sunlight
let sunlight = SunlightCalculator(latitude: 47.49801, longitude: 19.03991)
let officialDawn = sunlight.calculate(.dawn, twilight: .official)
let officialDusk = sunlight.calculate(.dusk, twilight: .official)
let civilDawn = sunlight.calculate(.dawn, twilight: .civil)
let civilDusk = sunlight.calculate(.dusk, twilight: .civil)
let astronomicalDawn = sunlight.calculate(.dawn, twilight: .astronomical)
let astronomicalDusk = sunlight.calculate(.dusk, twilight: .astronomical)
let nauticalDawn = sunlight.calculate(.dawn, twilight: .nautical)
let nauticalDusk = sunlight.calculate(.dusk, twilight: .nautical)
let blueHourStart = sunlight.calculate(.dawn, twilight: .custom(-8))
let blueHourEndGoldenHourStart = sunlight.calculate(.dusk, twilight: .custom(-4))
let goldenHourEnd = sunlight.calculate(.dusk, twilight: .custom(6))
```
## Install
Just use the [Swift Package Manager](https://theswiftdev.com/2017/11/09/swift-package-manager-tutorial/) as usual:
```swift
.package(url: "https://github.com/binarybirds/sunlight", from: "1.0.0"),
```
⚠️ Don't forget to add "Sunlight" to your target as a dependency!
